Switching device

Abstract

A mechanical switching device including a base member, at least one pair of elongated conductor members mounted on the base member, each conductor member with a conductor end, wherein the conductor ends of the pair of conductor members are separated by a gap, a middle member mounted on the base member, a switch member adapted to establish and disestablish an electrical connection between the conductor ends of the pair of conductor members. Each of the conductor members includes an opening in which a respective protruding part is received. The protruding parts are provided on and extend from the middle member so that the conductor members are electrically isolated and protected from the surrounding environment around the device.

1. A mechanical switching device comprising:
 a base member, 
 at least one pair of elongated conductor members mounted on the base member, each conductor member comprising a conductor end, wherein the conductor ends of the pair of conductor members are separated by a gap, 
 a middle member mounted on the base member so that conductor members of the pair of conductor members are covered by the base member and the middle member, wherein the pair of conductor members are protected from foreign objects that may cause a short circuit, 
 a switch member adapted to establish and disestablish an electrical connection between the conductor ends of the pair of conductor members, wherein each of the conductor members comprises an opening in which a respective protruding part is received, and wherein the protruding parts extend from the middle member so that the base member and the middle member, in cooperation with each other, are adapted to hold and electrically isolate the conductor members of the pair of conductor members from each other. 
 
     
     
       2. The mechanical switching device according to  claim 1 , wherein the middle member comprises clamping surfaces, each clamping surface acts on the respective conductor member of the pair of conductor members in a direction towards the base member. 
     
     
       3. The mechanical switching device according to  claim 2 , wherein each protruding part of the middle member extends from the clamping surface into the opening of the respective conductor member of the pair of conductor members. 
     
     
       4. The mechanical switching device according to  claim 1 , wherein at least one of the protruding parts comprises a first flat surface and a second flat surface, the first surface and the second surface are perpendicular to a longitudinal axis of the pair of conductor members, wherein the first surface and the second surface are directed away from each other. 
     
     
       5. The mechanical switching device according to  claim 4 , wherein the base member comprises a groove, the groove having a bottom surface supporting each conductor member and two separated side parts, each side part comprising a side surface, wherein the bottom surface and the side surfaces are perpendicular to a longitudinal axis of the groove, wherein each conductor member is in friction contact with each of the side surfaces. 
     
     
       6. The mechanical switching device according to  claim 5 , wherein at least a part of the groove comprises a guide member protruding out from at least one of the side parts and thereby preventing the pair of conductor members from displacement away from the bottom surface. 
     
     
       7. The mechanical switching device according to  claim 6 , wherein the guide member comprises a guide surface directed towards the conductor members, wherein each conductor member is in friction contact with the guide surface. 
     
     
       8. The mechanical switching device according to  claim 6 , wherein the pair of conductor members extends in parallel with a plane, wherein the guide member protrudes in parallel with said plane. 
     
     
       9. The mechanical switching device according to  claim 1 , wherein the base member comprises a groove that receives each of the conductor members at a certain position, in which position the respective protruding part of the middle member extends into the opening of the respective conductor member and thereby locking the conductor members of the pair of conductor members in the groove. 
     
     
       10. The mechanical switching device according to  claim 9 , wherein each conductor member is slidable in the groove along a longitudinal axis of the conductor member at least to the certain position. 
     
     
       11. The mechanical switching device according to  claim 9 , wherein the base member comprises a recess for each conductor member, wherein in the certain position of each conductor member the opening and the recess are positioned on a line and the respective protruding part of the middle member extends through the opening of the conductor member and at least into the recess of the base member. 
     
     
       12. The mechanical switching device according to  claim 1 , wherein at least one of the conductor members has the opening arranged on a side part of the conductor member. 
     
     
       13. The mechanical switching device according to  claim 1 , wherein the switch member is mounted on the middle member, wherein the middle member supports switch member.
